Articles and methods related to the cold-forming of glass laminate articles utilizing stress prediction analysis are provided. A cold-forming estimator (CFE) value that is related to the stress experienced by a glass sheet of a glass laminate during cold-forming is calculated based on a plurality of geometric parameters of glass layer(s) of a glass laminate article. The calculated CFE value is compared to a cold-forming threshold related to the probability that defects are formed in the complexly curved glass laminate article during cold-forming. Cold-formed glass laminate articles are also provided having geometric parameters such that the CFE value is below the cold-forming threshold.

The principles and embodiments of the present disclosure relate generally to complexly curved laminates made from a complexly curved substrate and a flat substrate, such as automotive window glazings, and methods of cold forming complexly-curved glass products from a curved substrate and a flat substrate. In one or more embodiments, the laminate includes first complexly-curved glass substrate with a first surface and a second surface opposite the first surface, a second complexly-curved glass substrate with a third surface and a fourth surface opposite the third surface with a thickness therebetween; and a polymer interlayer affixed to the second convex surface and third surface, wherein the third surface and fourth surface have compressive stress values respectively that differ such that the fourth surface has as compressive stress value that is greater than the compressive stress value of the third surface.

Automotive glazing, with electrically controlled light transmittance, has been available for a number of years. Growth has been steady as the public recognizes the added utility provided. While a number of means of implementation are in use, all require a set of electrodes spanning opposite faces of the switchable portion of the glazing. As automotive electronic content has proliferated and the glazed area of the vehicle has increased, it is becoming more and more of a problem finding a suitable location for the controls, for the switchable glazing as well as for other functions. By structuring the electrodes, touch sensitive regions can be formed on the laminate and utilized for control.

Embodiments of this disclosure pertain to a strengthened glass article including a first surface and a second surface opposing the first surface defining a thickness (t) of about less than about 1.1 mm, a compressive stress layer extending from the first surface to a depth of compression (DOC) of about 0.1.Math.t or greater, such that when the glass article fracture, it breaks into a plurality of fragments having an aspect ratio of about 5 or less. In some embodiments, the glass article exhibits an equibiaxial flexural strength of about 20 kgf or greater, after being abraded with 90-grit SiC particles at a pressure of 25 psi for 5 seconds. Devices incorporating the glass articles described herein and methods for making the same are also disclosed.

A sensor module includes: a base member; at least one of a single or a plurality of sensors and vibrators arranged on the base member, and a protective member constituted of at least one flat surface or a curved surface, provided so as to cover the at least one of the sensors and the vibrators. A part or whole of the protective member is formed of a strengthened glass and the strengthened glass is a chemically strengthened glass or a physically strengthened glass.
